. new and useful Improvements in Heel and Sole Blanks. specii'ication.

This invention relates to improvements in heels. whole soles and halfsoles for shoes and has for its object to provide cushion heels andsoles for shoes soconstructed that the weight of the body will begradually received by said heels and soles.

Another object of the invention is to provide rubber heels and soles forshoes so constructed that a very resilient bearing surface is obtained.

'ith the above and other objects in view, I have invented the deviceillustrated in the accompanying drawings in which- Figure 1 is a sideelevation of my improved shoe sole. Fig. 2 is a topplan view thereof.Fig. 3 a section on line A-A of Pi 2. Fig. l is a plan of a heel. Fig.5is a section on line C-C of Fig. i. Fig. (3 is a side elevation of arubber half sole. Fig. 7 is a section on line Bl3 of Fig. Fig. 8 is aSide elevation of an inner sole. and Fig. 9 is' a sectional view througha portion of a shoe showing my improved cushion sole applied thereto. 10is a transverse crosssectional view of a modified form of the invention.

Like reference characters indicate like parts throughout the followingspecification and in the several views in the drawings in which 1indicates a whole sole having the sole portion '2 the instep 3. and heeli, the said heel and sole portions having upstanding edges 3 and 6.which extend entirely around said heel and sole whereby a recess 7, isformed in th heel and a recess 8 is formed in the sole portion. In theserecesses are a series of integral upstanding. conical teats 9. the outerof which project very slightly and gradually increase in length towardthe central portion l() of the heel and the ball portion 1.1 of thesole: the longer of said teats being more pliant and the shorter onesbeing stili'er than said long ones. the weight of the body will begradually received by these teats which of which the following is aSpecification of Letters Patent.

will slowly bend under said weight thus producing an extremelysoft-cushioning effeet.

In Fig. 5 is illustrated a section of a rubber heel 12. which is formedin the same manner as the above d scribed heel. the teats 13 graduallyincreasing in length to the center ll, and when the-weight of the bodyis brought upon these teats they collectively assume a spiral position,and prevent any sudden ar to the heel of the wearer.

In Fig. 7 I illustrate the half sole 15, which is formed in preciselythe same man ner as the sole portion 2 illustrated in Figs. l, 2 and 3,and in Fig. 7 is illustrated a sole 16 which is adapted to be placedbetween an outer sole 17 and a leather insole 18 on the shoe 19; thissole 16 is relatively much thinner than the sole 2. but it is providedwith a series of teats said sole formerly described. I V

In Fig. 10 I show a modification of the device in which instead of usingconeshaped teats as used in the other forms of the invention. I providea sole 23 having an tip-standing flange Qltherearound. and upwardlyprojecting members 25 which are formed in stepped relation gradually increas ng in height to the part of the shoe where the greatest pressureis brought to bear.

It is to be noted that my improved soles, half-soles or heels may beused either as an outer sole or they. may be inte posed between theinsole and outer sole. Also. if desired. they may be used as an insolein which case they will be reversed. the teats projecting downwardly andcontacting the upper surface of an outer sole.

Having now described my invention. that which I claim to be new. andwish to procure by Letters Patent is:

1. A blank having heel and sole portions. each portion being providedwith a recess, and a series of closely scattered rubber teats extendingupwardly from the bottom of said recesses each of said teats beingsubstantially pyramidal in outline and having a rounded end, said seriesof'teats being so arranged as to be increased in length as they approachthe center of the heel and sole portions, respectively. the longest ofsaid teats projecting beyond the adjacent face of said heel and sole.

2. The described device consisting of a 20. formed in recesses in rubberblank having a recess, and a series In testi on) whereof I aflix mysignature of teats projecting from the surface of said in presence oftwo witnesses.
